Title:
SUPERCONDUCTING ELECTRIC ROTARY MACHINE
Document Type and Number:
Japanese Patent JPH01144356
Kind Code:
A
Abstract:
PURPOSE:To form a machine in small size and light weight by selecting high insulating fluid of nitrogen or the like as a refrigerant and forming a cooling structure with a refrigerant route in common for a stator and a rotor. CONSTITUTION:A machine is constituted of liquid refrigerant 1a of nitrogen or the like, field winding 2 formed by a superconductor of ceramic Y-Ba-Cu-O or the like, conveyer 3a and a center pipe 4 of the refrigerant 1a, low temperature rotor 5, normal temperature shield 6, normal temperature damper 6a, torque tube 7, heat exchangers 9-9b, radiating shield 10, collector ring 12, rotary shafts 13-13a, refrigerant discharge hole 17, armature winding 21, magnetic shield 22, stator frame 24, etc. And the refrigerant 1a is fed transferring into the rotor from a refrigerating machine system 33 through the conveyer 3a. While the refrigerant is attached by centrifugal force sticking to both internal peripheral sides of the low temperature rotor 5, circulating by natural convection between the field windings 2 and cooling the winding 2. Further the refrigerant is discharged also to a stator side from the two or more refrigerant discharge holes 17.
